To all whom it may concern.'

Beit knowrv that l, ei/'retrait luvntT Baumarten, a citizen of the United States, residing at ii/illiannsport, in the county of Lycoiningand State of Pennsylvania, have invented a nev. and useful Tire, of which the follhis invention relates more particularly to pneumatic tires for automobiles and like vehicles, and the principal object is to produce a tire that can be cheaply manufactured, is light and resilient, and has great powers for resisting the passage of articles, such as nails,

A Another important object is to` provides novel tire,

badly cut, the inner tube will be tightly bound, `and socalled blow-outs. thus prevented.

The `preferred form of construction is illustrated in Figure l. isa sectional view through the tire. Fig. 2 is alsoa sectional view through a different portion thereof. Fig. 3 is a plan view of a portion of the puncture-resisting cushion. Fig. 4 4is a sectional view through the tire, showing thersaid cushion in side elevation. Fig. 5 is a plan lview of a sheet of fabric, illustrating the manner of cutting the cushion strips. Fig. 6 is a plan view of a portion of the cushion with the secsaid sections broken away in order to illustratek several. Fig. 7 is a diagrammatic view, illustrating the manner in which the cushion is formed.

v Similar reference numerals designate corresponding parts in all the figures of the drawings.

ln the embodiment illustrated, an outer casing 8 is employed, which may be formed in any suitable manner, and is preferably reinforced by layers of fabric 9 incorporated therein. A lining l0 of rubber is also preferably employed, the lining having its lmarginal portions connected to the casing, and its intermediate portions free therefrom, forming an inclbsed pocket. While the lining l() is preferably a rubber sheet, it may be formed of a layer of the casing fabric secured along its'niargins to the casing. Within this pocket is located a puncture-resisting cushion, designated as a whole, by the reference numeral ll. ln producing this cushion, a sheet oi fabric, shown in Fig. 5, is employed, and is Cut upon the bias into a series of strips l2, said strips bcing of different widths. The strips are arranged end to' end, and are cemented together, as illustrated in Fig. 6. I The long strip, thus` produced, is Wrapped into a plurality of overlying convolutions, 4forming,independent layers.

Inthe-actual constructie?!` of the tire, the lining l0, Whether'a rubber sheet or faerie, as described is first placed upon a forni or mold, the strip is then iifrapped upon the same, and the casing aiterwards formed about .i

the strip. The layers are separate from one another,

and are notcementedor secured together into a single extremely fiexibletire is provided, the cushionwithin the saine being very mobile, and when the tire is in place, and inflated by an inner tube, this cushion is very securely maintained in position, as shown in Fig. 2. Should a nail or other sharp article'pierce the harder outer casing, it-'I'Willfof coui'se strike the fabric of the cushion, and the different layersthereof being very flexible because of their independence, and because of being cut'upon the bias, `will givefreely. Therefore if the inward'pres'sure against the said article exceeds the outward pressureof the air in the inner tube, said inner tube will merely beforeed inward, as shown in Fig.`l. In this action, the first outer layers may bel pierced, but the peculiar bend given to them an air pressure of substantially eighty pounds to the square inch. At the same'time, the cushion effectively binds the inner tube entirely independent of the outer casing portion, and thus if said casing portion is cut, the fabric layers will not only protect the inner tube, but will still conine'the same and prevent the .so-called blotwouts, of such common occurrence in the heavier class of pneumatic tires.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further. description, and will be understood that various changes in the size., shape, proportion and minor details of construction, may be resorted` to Without departing from the spirit or sacri-` comprising a strip wound longitudinally upon itself into :i plurality of convolutions, one overlying the, other, said strip consisting of sections disposed end to end, the end'of one section being secured to the eud of the next;

2. ln a tire, the combination with an outeiicasing, of a punctuiercsisting cushion located inside the sume and comprising a strip wound longitudinally upon itself into a plurality of convolutions, one overlying the other, said strip consisting of sections successively less in Width and disposed end to end, the end of one section being secured to the end of the next, and said convolutions having their adjacent faces free one from the other.

In a' tire, the combination with an outer casing, of a puncture-resisting cushion located inside the same and comprising a plurality of independent layers of fabric laid one on the other and having their margins only secured together at'intervals, the portions between said fastened parts being,r free from one another.

4. In a tire, the combination with an outer casing, of

. a puncture-resisting cushion located inside the same and comprising a plurality of independent layers of fabric laid one on the other, and spaced transverse binders extending over the strips at intervals, said binders being secured to the margins of the layers only V.and having their intermediate portions free from said 'slayers.

5. In a tire, the combination with an outer casing, of a puncture-resisting cushion located inside the same and comprising a plurality of independent layers of wovenfabric laid one on the other and cut on the bias, said layers Ihaving their margins only secured together at intervals,

and spaced transverse binders extending over the strips4 at their points of marginal attachment, said binders having their intermediate portions free from the strips.

6. In a tire, the combination with an outer casing, of a puncture resisting cushion located inside the same and comprising a strip of fabric separate from the casing and wrapped longitudinally into aA plurality of layers, one overlying the other. Y

7, In a tire, the combination with an outer casing, .of a puncture-resisting cushion located inside the same and comprising a strip of fabriewrapped longitudinally into a plurality of, longitudinal overlying convolutions and comprising sections of diierent widths.

8. In a tire, the combination with an outer casing, of a punctureresisting cushion located inside the same and comprising a strip of fabric cut on the bias, said strip being wrapped longitudinally into a plurality of separate overlying vconvolutions.

5). In a tire,'the combination with an outer casing, of

a punctureresisting cshion locatedv inside thev same and comprising a strip otfabric cut on the bias, said strip being Vwrapped longitudinally into a plurality of separate overlying convolutions and comprising sections f different widths, each strip atyone end being secured to theend of the next strip.

' 10. In a tire, the combination with an outer casing, of an inner lining having its margins secured to the casing and forming an interior pocket, and a puncture-resisting cushion located inside the pocket and comprising a strip of woven fabric cut upon the bias and composed oi' sections of different widths, said strip being wrapped longitudinally into a plurality of overlying convolutions forming independent layers. means securing the margins only of the layers together at intervals, and leaving the intermediate portions'free, and binding strips connected to the margins only of the layers at their points of attachment, said strips extending transversely over the layers.

In testimony, that I claim the foregoing as my own, I have hereto aiixed my signature inthe presenceof two witnesses.
